Contributing to PyMongo

PyMongo has a large community and contributions are always encouraged. Contributions can be as simple as minor tweaks to the documentation. Please read these guidelines before sending a pull request.

Bugfixes and New Features

Before starting to write code, look for existing tickets or create one for your specific issue or feature request. That way you avoid working on something that might not be of interest or that has already been addressed.

Supported Interpreters

PyMongo supports CPython 2.4 and newer, PyPy, and Jython. Language features not supported by all interpreters can not be used (e.g. the with statement is not supported in Python 2.4). Please also ensure that your code is properly converted by 2to3 for Python 3 support.

Style Guide

PyMongo follows PEP8 including 4 space indents and 79 character line limits.

General Guidelines

  • Avoid backward breaking changes if at all possible.
  • Write inline documentation for new classes and methods.
  • Write tests and make sure they pass (make sure you have a mongod running on the default port, then execute python test from the cmd line to run the test suite).
  • Add yourself to doc/contributors.rst :)


To contribute to the API documentation just make your changes to the inline documentation of the appropriate source code or rst file in a branch and submit a pull request. You might also use the github Edit button.
